What is the unit of electric current?

The unit of electric current is the Ampere. Electric current is defined as the flow of electric charge in a circuit, and the Ampere quantifies this flow. One Ampere corresponds to one coulomb of charge passing through a point in a circuit per second. This is a fundamental unit in the International System of Units (SI) and is crucial for understanding how electric circuits operate.

The other choices represent different electrical quantities:

• Volt is the unit of electric potential or voltage, which measures the difference in electric potential energy per unit charge.

• Watt is the unit of power, indicating the rate at which energy is consumed or produced in a circuit.

• Ohm is the unit of resistance, measuring how much a material opposes the flow of electric current.

Understanding these distinctions helps clarify why the Ampere is specifically the correct choice for the unit of electric current.
